Can me the positive reviews only agree: The glass makes it possible to shoot clear, sharp images even at high ISO speeds. I currently have only the comparison with the 18-55mm kit lens: You either do not work or clean but the lack of sharpness is simply konstrukitonsbedingt. The basic focus of the '50s (eg aperture f2.8) also has ISO 3200 and ISO 6400 very positively to the overall impression of the image and the kit lens übertifft clear what already matscht at significantly lower ISO values. Otherwise, it's fun to have flexibility with respect to the aperture and the blurring Bildkompositorisch targeted use.
++++ Focus ++++ Aperture latitude +++ Low ++ Sufficiently stable + - Autofocus loud and not always very precise
